To all whom it may concern:

Beit known that LCERISTIAN J LANN, a citizen of the United States, residing at Seattle, inthe county of King and State of WVashington, have invented a certain new and useful Improvement in Stoves, of which the following is a specification.

My invention relates to improvements in stoves that are adapted for use on shlpboard or in similar places where they aresub- ,jected to a tilting or rocking. motion and the object ofiny invention is toprovide a stove that is supported on gimbals which gimbals are mounted within a frame in such manner that the top of the stove will always remain in a horizontal position regardless of the angle atwhich the frame is turned.

A further. object is.v to provide a novel frame structureand a novel arrangement of gimbal joints that are particularly adapted for supportin -v an oil stove. i

A still further object is toprovide simple and easily operated means for grasping and holding a cooking utensil that is placed on the stove.

Another object resides. the provision of means for locking the gimbal ringsto the frame to render. them inoperative thereby maintaining the .top of the stove in a horizontal plane.

My invention consists in the novelconstruction, adaptation andflcombination of parts as will be more clearly hereinafter described and claimed.

I. accomplish these objects devices illustrated in the accompanying drawings, where.

.The gimbal ring 15is provided at two diai metrically opposite pointswith depending lugs 16, said lugs 16 beingpositionedfat the: v 7

front and rear sides of the frame respectively and the lugs 14 on the circular frame member,

being disposed at right angles tothe lugs 16. 17. is a ring. shaped membenl as shown in Fig. 5-, that is connected at four equally spaced intervals withbrackets, 18 .which ,are secured to and support a weight 19, said brackets 18 beingenlarged and'flattened. as at 20 at the front and rear sides of the stove where they are connected to the ring 17; said brackets 18 project upwardly and outwardly from the top surface of such ring 17 to afford a means of connection with pivot pins 22 that pass through the lugs 16. o 7

By the arrangement just described it will be readily understood that a universal joint connection is formed so that when the supporting frame is tilted in any direction the gimbal ring 17 which forms a stove grating will always be held in a horizontal position, a weight acting as a pendulum and always tending to hang vertically.

Supported upon the weight 19 and fixedly secured thereto is an oil receptacle 23 having an upwardly projecting pipe 24 that is connected at its top end with an oil burner 25 of any suitable type and is provided below the oil burner 25 with a pan 26 for the reception of oil that is used for heating the burner when the latter is first lighted.

Extending into the top of the oil recep tacle 23 is a pump 27 of the reciprocating type having a handle 28 that projects outwardly from one side of the'receptacle 23 and is adapted to rest upon and behind one of the brackets 18 as more clearly shown in Fig. 1, when the pump is not in use the bracket 18 preventing the handle 28 from being moved outwardly by j olting or tilting motion of the stove. J

*The oil receptacle '23 is provided with. a suitable inlet opening 30 through whichfuel may be introduced and with an air control valve 31 of well known form by which an excess pressureof air may be let out of the receptacle 23. The specific construction of the oil burner forms no part of this invention so that it will not be herein described in detail. 3

The ring member 17 is preferably substantially square in crosssection and is provided with a centrally disposed ring portion 32 that is rigidly'connected to the outer ring 17 by radially disposed integral'guide'meia bers 33 each being provided with a slot 34.

Mounted on the guide members 33 and projecting upwardly therefrom are utensil engaging brackets 35 each of which is provided with a shank 36 adapted to project downwardly throughthe slots 34 and with other shanks 37 and 38 adapted to project downwardly on the outer sides of the guide members 33. The rear side of each of the cam ring comprising an outer or rear por-,

tion 41 that is connected with'the hub portion 42 by integral curved grooved spoke members 43, each of which is provided with a curved cam slot 44 that is adapted to fit over the lower end of the shank 36 on one of the brackets 35 so that when the cam ring is rotated with respect to the member 17 the brackets 35 will be moved lengthwise along the guide members 33 and may be caused to engage with the sides of a cooking utensil and rigidly support the same.

' The cam ring is disposed directly below the gimbal ring 17 and is adapted to fit into suitable recesses 45 in the lower part of the gimbal ring which form a bearing for the cam ring so that it may be turned with respect to the gimbal ring, the shanks 36 being threaded and having nuts provided thereon below the cam ring so that the latter is held upwardly against the gimbal ring 17. The cam ring is provided with assuitable downwardly projecting lug or handle 46 by which it may be turned. I

The bearings between the lugs 14 and the,

ring 15 and the lugs 16 andring 17, respectively, are preferably roller bearings, as shown in Fig. 8 and the pivot pins 21 and 22 are inserted through the lugs 14 and 16 respectively and screwed into the ring 15 or lugs 20 as the case may be, and locked therein by set screws 47. Thevroller bearings make the device extremely sensitive to any tilting movement of the frame.

To prevent the stove from swinging like, a pendulum within the frame when it is sub jected to vibrations or lurchingrmovements but not'tilting movements I have provided two springs 48 and 50 respectively, the spring 48 being fixedly secured to the lugs 16 at the rear of the stove thence extending downwardly, as shown in Fig. 3, to a point opposite the burner body where it is pro-s vided with a forked end 48 that fits over the adjacent bracket 18, the spring 48 being strong enough to prevent the stove from swingingvin pendulum fashion but not be ing strong enough to cause the stove to be tilted when the frame is tilted.

The spring 50 is secured to one of the lugs 14 and projects in both directions therefrom, the outer ends of such spring being provided with rollers 51 that are adapted to bear downwardly on the top of the ring. member 15 to act in a manner similar to,

the spring 48 and prevent the stove from swinging in pendulum fashion within the flame, but not to prevent it from remaining in an upright position when the frameis tilted.

In some instances it may be desired to lock the stove fixedly to the frame so that it cannot swing with; respectthe reto and for this purpose I provide three lugs 52, 53 and 54 which are rigidly secured to thefr'ame ring 12, the gimbal ring-15 and the gimbal ring 17 respectively, in substantial aliuesecurely lock the'frame ring 12, the gimbal.

ring 15 and the gimbal ring 17 together and prevent, relative movement therebetween.

The operation of this device isextremely simple, the weight 18 and the fuel receptacle 23 acting like the weight of a pendulum to always maintain the gimbal 17 which serves as a stove grating in a horizontal position regardless of the tilt that is imparted to the supporting frame.

The gimbal ring connections constitute universal joint whlch permits the ring 17 to remain horizontal regardless of the direction in which the frame is tilted.

This stove is especially designed for use on ship board and various parts are proportioned so that they will allow sufficient movement to compensate for rolling and lurching of a boat under any conditions.

The brackets or lugs 35 for clamping the cooking utensils upon the top of the stove plate or ring 17 prevent such utensils from sliding over the top of the plate when the vessel lurches sidewise or when a quick movement in any direction is imparted to the stove.

In Fig. 9 I have shown by a view in perspective a duplex frame for supporting a plurality of stoves of the type'shown in the preceding figures. Such frame preferably comprising two lower rings 56 and two upper rings 57 supported from the lower rings 56 by leg members 58, the upper rings 57 be ing cut away at the front side of the stove as herein before described in connection with the ring 12;

lVhere the two rings 56 and the two rings 57 are joined they are preferably secured to each other by cross bars which may be welded thereto and the leg members 58 for the adjoining sides of the rings being connected with the cross members 60 so that two of the leg members 58 will serve to support the adjacent sides of two frame rings.

It will be readily understood that any number of frame rings may be connected together in the manner shown in Fig. 9.

Figs. 10 and 11 show a rectangular oven provided with an upper compartment 61 and a lower compartment 62 that are separated by a shelf 63 and having a door 64 on its front side.

The bottom side of the oven is provided with an opening 65 adapted to fit over the burner of the stove shown in Figs. 1 to 8 and the compartment 62 is provided with a curved bottom section 66 preferably of fire brick or similar material that arches upwardly over the opening 65 as shown in Fig. 10.

The oven may be provided on its top side with a suitable handle 67 by which it may be: carried and such oven ispart i'oula-rly adapted'for usev on the typeof stove shown in Figs. 1 toS.

In F igsl. 12 and 13 Ihave shown a heat retaining device comprisingflan outer: semispherical shell 68 havingv a Hat bottom side 70 wherein is provided a central opening 71 that is adapted to fit over the burner 25 when the head retaining member is placed on the stove burner, as shown in Fig. 6. The 7 head retaining member is. lined with fire brick or similar composition, that portion of the fire brick above the opening 71 being arched as at 73 and the fire brick being so arranged that an internal air chamber 74 is formed. The shell 68 is provided on its top side with a suitable eyelet 75 by which it may be carried. 7

This shell may be placed on the stove shown in Figs. 1 to 8 inclusive and allowed to become intensely heated and it may then be removed to any desired location and will serve to give its heat slowly and for a long period of time.

Obviously changes, may be made in the forms, dimensions and arrangement of parts of my invention without departing from the spirit thereof.
